This bridge is one of three movable bridges, for where opening and closing are controlled by an automatically operated system.
The boat captain starts operation of the bridge’s system. This bridge does not require any operating personnel. There are maintenance employees trained to Service and respond to any operating failures. Failure alarms are automatically sent to the maintenance firm by a telephone-robot. The bridge consists of two parts a movable single-leaf bascule orthotropic steel bridge and a two-span fixed bridge. The fixed part is a composite girder bridge with a reinforced concrete deck. Its spans are 24 m + 18 m. The leaf spans 12.0 m. The horizontal navigation clearance is 8.6 m, and the clear headway 3.5 m. The orthotropic span is a grid structure with two main steel girders. Transverse girders at center-to-center at 2 m. and a deck plate with longitudinal stiffeners. The forward end of the leaf rests on an elastomeric pad- bearing and at the abutment end it is supported by
two fixed spherical trunnions (steel spherical sliding bearings). In addition to the trunnions, the leaf is in the opening and closing stage, is supported by hydraulic cylinders at each main girder. The maximum opening angle is 81 degrees. A hydraulic drive unit run by an electric motor supplies the operating force for the cylinder. During the sailing season, the temperature of the hydraulic oil is kept at or above a minimum of +20°C by a heater equipped with a thermostat.
